Aerating a lawn involves putting small holes in the ground and plugging hard clay out of lawns. This allows moisture to go back into the grass and nutrients to penetrate the grassroots. Lawns should be aerated twice a year. Aerating costs $35 and up.
During the spring, I apply Spring Organic Rich, a pet-friendly fertilizer to your lawn. In the summertime, I use Scotts Summer Guard (which is not pet-friendly) or Scotts Turf Builder, depending on your yard's needs. Rich lawn winterizing fertilizer is used during the fall. Fertilizing in the summer costs $40 and up. Fertilizing costs $35 and up during the spring and fall.
